Github SSH Setup

Steps

1. Generate SSH Key on Jenkins Server

Run the following command on the Jenkins server to generate an SSH key:

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

2. Add Public Key to GitHub

After generating the SSH key, add the public key (id_rsa.pub) to your GitHub account under SSH and GPG keys in the settings.

• Go to GitHub and log in to your account.
• Click on your profile picture in the top right corner and navigate to Settings.
• Scroll down to the SSH and GPG keys section and click on New SSH key.
• Give your key a descriptive title, such as "Jenkins Server".
• Copy the contents of your id_rsa.pub file and paste it into the Key field.
• Click Add SSH Key to save the changes.

3. Modify SSH Config

Create or modify the ~/.ssh/config file to use the generated SSH key when connecting to GitHub. Add the following:

Host github.com
  User git
  IdentityFile /path/to/your/ssh/key

4. Test SSH Connection

Test the SSH connection to GitHub using the following command:

ssh -T git@github.com

5. Create Credentials in Jenkins

To create credentials in Jenkins, perform the following steps:

• Navigate to Jenkins and log in.
• Go to Manage Jenkins > Manage Credentials.
• Under (global), click (Add).
• Click on Jenkins.
• In the kind field, choose SSH Username with private key.
• Enter the ID, Description, and Username (usually git for GitHub).
• For the Private Key, choose Enter directly and paste the contents of your private key (id_rsa) file.
• Click OK to save the credentials.

6. Configure Jenkins

In Jenkins, configure the project's source code management to use SSH when pulling from GitHub.
